APPARATUS FOR EXTINGUISHING THE FIRES lN RAILWAY-CAR STOVES.

SPECIFICATION forming part of Letters Patent No. 399,398, dated March 12, 1889.

Application filed February 23, 1888: Serial No. 264,891. \No model.)

To aZZ whom it nu/y GONG/37711.

Be it known that we, ROBERT HOW'HG GIL- MOUR and FORTUNATL'S GALBRAITHKELLOGG, both of Huntington, in the county of Huntington and State of Indiana, have invented a new and Improved Apparai us for l lxtinguishing the Fires in RailwayCar Stoves, of which the following is a full, clear, and exact description.

This invention relates to a novel device to be employed in railway-ears, whereby in case of collision the fires in the stoves or heaters on a train may be instantly extinguished and the cars thereby prevented from catching fire.

The invention consists in. an apparatus for this purpose constructed and arranged as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in both the views.

Figure 1. illustrates, with parts in section, an apparatus constructed in accordance with this invention. Fig. 2 is a detail in horizontal section on the line .1? o: of Fig. 1.

In carrying out this invention an apparatus is located in each car and connected with the engine and the stove in the car, so that the engineer can extinguish at will the fire in the stoves on a train by causing water or chemi ca] '5 to be discharged into the stoves. Each car is provided with an air-chamber and a chamber containing water or chemicals, each chamber having a cylinder, piston, and valve and being connected by pipes with each other and the canstoves, which pipes connect with a main pipe leading to an air-reservoir on the engine. The air in the air-chamberis held therein by the pressure 01? the air from \Vhen this the air-reservoir on the engine. pressure is cut off by the engineer, the air in the air-chamber automatically released, opens a valve closing the water-chamber, and forces the water or chemicals into the stove, thereby extinguishing the fires.

1 indicates the water-chamber, and 2 the air-chamber. The chambers 1 and 2 may be of any suitable size and shape and are located in any convenient part of a car and supported by suitable brace-rods or brackets (not shown) fastened to the side or floor of a car. The water-chan'1ber 1 communicates with a cylinder, 4, formed by means of the parts 5 i 7, screwed together and opcninginto chamber 1, by means of a passage-way, 8, in part 7. The cylinder l is provided with a piston, .1, having a valve, 10, at its end,whichis normally held seated in opening 11 by a spring, 12, located between piston-head 13 and the upper end of the cylinder. An opening, 14:,at the upper end of cylinder .4- connects by means of pipe 15 with a pipe, 10, leading to the top andbottom of a car-stove, 17, and communicating with the top and bottom of the fire-box. An. opening, 18, islocated in cylinder 4, just above the 1 )iston-head13, and is provided with a pipe, 19, leading to an opening, 20, in the top of chamber 1.

21. indicates a chamber or boxing for the admission of water or chemicals supplied to chamber ,1. The boxing 21 is closed by cover 22, with handle the cover being formed with screw-threaded portions 21, engaging corresponding threaded. portions, 25, of the boxing 21. i The cover is secured in place by the screw threaded portions 2i being pushed down in slots 25 in the sides of the boxing 21, and then giving the cover a partial turn, when screw-threaded portions it are thrown into engagement with their corresponding portions, 25, in boxing 21.

The lower end of cylinder i has an opening, 26, which connects by a pipe, 27, with an opening, 28, adjacent to the upper part of a cylinder, 29, formed of the parts 30, 31, and 32, screwed together.

An opening, 33, in the lower end of cylinder 29 is normally closed by means of a valve, i 31,011 the end of apiston, 35, having a spring, 36, located between the end of the cylinder and the piston-head 37. In normal position the latter is located just above the opening The upper end of cylinder 2!) communig cates with air-chamber by means of a pas i sage-way, 38, in part 32. The lower end of l cylinder 2.) has an opening, 39, which coni nects by means of a pipe, 40, with the main air-pipe 4:1, located beneath the car-floor 42. The main pipe e1. leads to an air-reservoir on 3 the engine,and is connected between the cars .by suitable couplings. The air-supply is regulated by a valve or cook on the engine under control of the engineer.

A pipe, 43, leads from pipe to the top of air-chamber 2 and communicates with the interior thereof.

44 indicates an au-ton'iatic reacting valve, which remains open when there is air-pressure through tube 41 into chamber 2. The valve 44 normally lies against cross-wires :3 in chamber at.

The operation of the apparatus is as follows: ater or chemicals having been placed in chamber 1, air is supplied. from the reservoir on the engine at a pressure of about sixty pounds to the square inch. The air passes through pipes 41 4.0 4 3 to chamber and through passage 38 to the upper end of cylinder 20. It also passes through passage 39 into the lower end of cylinder 29. Thepressure of the air holds valve 441- open and is equal against piston-head 37 and valve 34, so that piston remains in itsnormal position, as shown, the diiference of pressure due to the difference of: areas of the piston-head and valve being counterbalanced by the spring. Vhen a collision is seen to be imminent the engineer cuts off the supply of air from the reservoir on the engine, which withdraws the air-pressure from pipes 41, 40, and 4:3 and passage 39 and causes the air under pressure in chamber 2 to react. air in chamber 2 closes valve 4A and forces the piston-head 37 down below the opening 28. The air then passes through pipe 27 and openin 20 into the lower end of cylinder 4, lifts the piston-head 13 above opening 18, passes through pipe 19 into chamber 1, and drives out the water or chemicals therein through passage 8, openin 1 4:, and pipes 15 and 16 to the interior of stove 17, extinguishing the fire therein. The piston-head 13, when lifted by the pressure of air, as above described, will be held raised by the diliierence of pressure due to the difference of areas of the valve 10 and piston-head 13.

Each car being supplied with this apparatus, it will readily be seen from the foregoing description that all the tires in the stoves of a train may be instantly extinguished.

\Vhile a specific construction and arrangement of apparatus has been set forth, it is not intended to limit the intention thereto, as the parts may be modified and arranged without departing from the principles of the invention to accomplish the same result. It is obvious that a single connection may be used with the stove instead of a double one, as shown, and that the water or chemicals may be admitted into the stove by any desirable form of discharge-pipe.

The apparatus is adapted to operate auto- .matically as well as to be set in motion by the engineer, as in case of a collision or derailment, upon the breaking of the main air pipe or its couplings, the apparatus will op" erate to extinguish the fires in the stoves.

Haw-*ing thus described our invention, we
